MULTIWATT11
ORDERING NUMBER: TDA2004A
PIN CONNECTION (top view)
Its main featuresare:
Low distortion.
Low noise.
High reliabilityof the chip andof the package with
additionalsafety during operation thanksto protec-
tions against:. OUTPUT AC SHORT CIRCUIT TO GROUND. VERY INDUCTIVE LOADS. OVERRATING CHIP TEMPERATURE. LOAD DUMP VOLTAGE SURGE. FORTUITOUS OPEN GROUND
Space andcost saving :very low numberof exter-
nal components,very simple mounting system with electrical isolation between the packageand the
heatsink.
DESCRIPTIONThe TDA2004Aisa classB dual audio power am-
plifierin MULTIWATT package specifically desi-
gnedforcar radio applications;stereoamplifiersare
easily designed using this device that providesa
high current capability(upto 3.5A) and that can dri- very low impedance loads (downto 1.6Ω).
